[Bug 1943906] Re: warning about missing firmware is mostly just noise

[Benjamin Drung]

initramfs-tools 0.142ubuntu11 in mantic uses dracut-install for
installing the kernel modules (see bug #2031185) and those warning are
gone now.

Title:
  warning about missing firmware is mostly just noise

Status in initramfs-tools package in Ubuntu:
  Fix Released

Bug description:
  Every time an LTS release gets a new backport kernel, we see reports
  from concerned users when they see something like this:

  W: Possible missing firmware /lib/firmware/i915/skl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/bxt_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/kbl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/glk_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/kbl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/kbl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/cml_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/icl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/ehl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/ehl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/tgl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/tgl_guc_49.0.1.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/dg1_dmc_ver2_02.bin for module i915

  and since we don't do full backports of linux-firmware this is just
  noise for the users. Could there be a way to warn only during the
  development phase? That way the missing firmware would more likely get
  added for the primary kernel prior to release, but not warn when using
  a newer backport/mainline kernel.

  (in this case the guc firmware would be pointless to add to l-f, since
  while they would be loaded, the feature they add is not enabled by
  default)
